Hello,
I am working on a EC25-1 which has problem with the USB communication with a dwc2 usb host controller [1]. To find the problem my next step was to connect to the EC25 debug UART on pin 11/12. But the system needs a root password! The one you have on your wiki does not work anymore [2]. I think I have the same version "msm LNX.LE.5.0.1-57031-9x40 mdm9607-perf /dev/ttyHSL0" Do you have another password for this interface or where did you get this information from?
Thanks for help Flo
